evolution of superconductivity in lao1 xfxbis2 prepared by high Pressure Technique
EPL, 2013Co-Authors: Keita Deguchi, Yoshikazu Mizuguchi, Satoshi Demura, Hiroshi Hara, Tohru WatanabeAbstract:Novel BiS2-based superconductors LaO1−xFxBiS2 prepared by a high-Pressure synthesis Technique were systematically studied. It was found that the high-Pressure annealing strongly shrank the lattice as compared to the LaO1−xFxBiS2 samples prepared by conventional solid-state reaction at ambient Pressure. Bulk superconductivity was observed within a wide F concentration range of x = 0.2–0.7. On the basis of those results, we have established a phase diagram of LaO1−xFxBiS2.

fast dynamic interfacial tension measurements and dilational rheology of interfacial layers by using the capillary Pressure Technique
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2012Co-Authors: Aliyar Javadi, Alexander V. Makievski, Jürgen Krägel, P. Pandolfini, Giuseppe Loglio, V I Kovalchuk, N M Kovalchuk, N Mucic, Mohsen Karbaschi, Reinhard MillerAbstract:Abstract The oscillating drop and bubble analyzer (ODBA) is an experimental set-up based on the measurement of capillary Pressure under static and dynamic conditions. It allows studies of slow and fast dynamic surface and interfacial tensions, following different growing and oscillating drop or bubble protocols, as well as determination of the dilational interfacial visco-elasticity of liquid interfacial layers. For the visco-elasticity studies, drops or bubbles are subjected to harmonic oscillations of area or volume in a broad frequency range, and the resulting harmonic capillary Pressure response is analyzed by Fourier analysis. Also, transient relaxations can be easily performed, which are of particular importance for isodense systems. The limits of applicability for highly dynamic conditions are given by the hydrodynamics of the fluid flow inside the capillary tip and the Pressure cell which depend on fluid properties, capillary tip size, and geometry. For the growing drop protocol, additional phenomena during drop formation and detachment play a significant role. For oscillating drops or bubbles, the highest accessible frequencies also depend on the absolute drop size and applied oscillation amplitude. In this work, the capability of the Technique for measurements in the frequency range between 1 and 100 Hz are discussed, and elasticity values at up to 80 Hz were measured for the liquid–liquid interface.

Dynamic interfacial tensions in the short time range by applying a fast capillary Pressure Technique
Microgravity Science and Technology, 2006Co-Authors: Alexander V. Makievski, Jürgen Krägel, P. Pandolfini, Giuseppe Loglio, Libero Liggieri, Francesca Ravera, Eva Santini, Martin E. Leser, Martin Michel, Reinhard MillerAbstract:The capillary Pressure Technique is the method of choice for any tensiometry measurements in microgravity, as all bubbles and drops have a spherical shape. A combination of fast drop formation based on a known constant liquid flow and fast data acquisition of measured capillary Pressure gives access to dynamic interfacial tensions in the range of milliseconds. Also the maximum drop Pressure method, an equivalent to the maximum bubble Pressure Technique as fastest dynamic surface tension method, can be practised by the same set-up. The Technique was developed already 15 years ago [ii] and now further refined during the MAP FASES* supported by the European Space Agency [ii]. Besides a detailed description of the technical parameters, experimental results for emulsion relevant systems are presented. The set-up presented here is based on a commercial drop and bubble profile analysis tensiometer which appears to be a kind of in-situ Technique for membrane emulsification processes. The instrumental set-up is suitable also for oscillating drop and bubble experiments up to frequencies of several hundreds Hz.
